We already know your chart of accounts.
340 mandates concentrate in six sectors. That focus means your bookkeeper has seen your exact VAT question before — probably this month.
Trades and construction
Work-in-progress valuation, per-project margins and subcontractor withholding — handled monthly, not discovered at year-end.
Gastronomy
Daily cash reconciliation, tips and staff-meal accounting, and the split VAT rates that trip up every new restaurant.
Medical practices
TARMED receivables tracking, locum payroll and the pension-planning questions every practice owner eventually asks.
Agencies and consultants
Project profitability, unbilled-hours accruals and clean expense policies that survive both the auditor and the client.
E-commerce
Marketplace settlement reconciliation, EU OSS registrations and inventory valuation across warehouses and platforms.
Associations and NPOs
Fund accounting, tax-exemption filings and treasurer handovers documented so the next committee inherits clean books.
Trades and construction
94 mandates · since 1998
A painter with three crews does not need an audit firm — they need someone who books materials against the right project every month and warns them in October, not April, when a job is running below margin. We reconcile WIP monthly, keep subcontractor documentation audit-ready, and prepare the year-end so the bank renews the equipment line without questions.
Typical package: Ledger + Payroll, CHF 340/mo for a 6-person firm.
Gastronomy
61 mandates · since 2003
Restaurants fail on cash discipline, not cooking. We reconcile the till daily against POS exports, account for the 2.6% and 8.1% VAT split correctly from day one, and run payroll for kitchens where half the team is paid hourly with irregular shifts.
Typical package: Full mandate, CHF 620/mo for a 40-seat restaurant.
E-commerce
43 mandates · since 2016
Marketplace payouts arrive net of fees, refunds and reserves — booking them as revenue is the most common error we clean up. We reconcile settlement reports line by line, handle Swiss import VAT and EU OSS filings, and keep inventory valued consistently across your warehouse and fulfilment partners.
Typical package: Ledger, CHF 180/mo plus per-receipt volume.
They caught a five-figure VAT error our previous fiduciary had repeated for three years — and filed the correction before the FTA ever asked.
